COLING AND HEATING SYSTEM FOR AUTOMOBILES.

Application led January 2, 1925. Serial No. 240.

citizen of the United States, and residing at Bedford, in the county of Cuyahoga` and l*State of Ohio, have invented certain new and useful Improvements in a Cooling and I-Ieating System for Automobiles, of which the following is a specification.

My invention relates to an improvement in a combined cooling and heating system' for automobiles operated by internal combustion engines, and in general my object is to provide a simple hot Water circulating system for heating the vehicle to comfortable temperatures in cold Weather by utilizing apart or all ofthe water heated by the engine. The invention is also particularly designed to circulate the hot water from the engine through the heaters in the car or the water cooling radiator at the front ot the car alternatively, and-to cause the water passing through the engine to 'be diverted automatically through the cooling radiator when the water becomes too hot for lefficient operation of the engine.

In the accompanying drawings, Fig. 1 is a schematic view of an automobile embodyculaton of waterrs caused by the heat gening an internal-combustion engine having a gravity ow cooling and heating system constructed and arranged according to my invention. i Y

Fig. 2 is an enlarged sectional lview ot the valved by-pass elbow used in my apparatus, and Fig. 3 is a sectionalxview of the,

automatic device used at the water return manifold forcontrolling the by-pass valved shown in Fig. 2. Fig. 4 is a schematic drawing of an'automobile embodying a pump operated circulating system constructed and arranged according to my invention.

The present invention involves an auto mobile orI other vehicle'2 in which an internal combustion engine 3 is used having a water jacket 4 through which a cooling medium, such as water, is circulated while the engine is running.` The water is cooled bydischarging it from the top of the engine through a pipe connection 5 leading tothe upper end of a cooling radiator, and thence from the lower end of theradiator back to the engine by Way ofl a return pipe7 which connects with a detachable manifold or coupling vmember at one side of the water jacket. Insome types of engines the cirlheater pipe 18 when l through the heater is not desired. A lug Or 'within cap 9 opposite a lateral out-let port and pipe 11, (see Fig. 3). Thermostatic element T is provided with a vertical stem l2 which extends through a. packing gland 13 in the top of cover 9 where the short arm 14 of a pivoted lever 15 is adapted to be loosely engaged and raised by the stem when the thermostatic element is heated and expanded by hot water returning at high temperature to water-jacket through coupling member 8 by way of return ipe 7 from cooling radiator 6 or by Way o? return pipe 11 from the heating coil 16 within thevehicle. To eii'ect circulation of the hot water through heater 16 I provide al separate elbow member 17 at the outlet endof the water jacket Ot the engine and connect an intake pipe 18 for the heater with a lateral t branch 19 on elbow member 17. A pivoted valve member 20 Within this elbow member is adapted to Idivert the flow of water either to the radiator pipe 5 or to the heater pipe 18, dependent upon conditions inthe engine manual operation is effected by an operating rod 22 which connects with one arm of the bell crank 21 and extends into the interiorl of the car where the driver may press itinward-to'close the by-pass branch 19 and wcatch 23 may be .iXed .on rod 22 adjacent the edge of a slotv24 in the instrument board 25 so that when the rod is pressed lnward at its limit the catch `will hold the rod against 105 a return movement providing it is permitted to 'gravitate intov locking engagement with the bottom edge of slot 2 4. `Automatic Operation O valve 20'is effectedl by a link 26 connected'to thelong arm Qf lever 15 which `is y110 aow of hotwater lals .1n contact witlrvertical stem 12 of thermostatic element T. As a result whenever the water in the engine jacket 4 becomes too hot it will cause the thermostatic device to tilt lever 15 and open the outlet 28 leading to the cooling radiator, thereby establishing a How of hot water from the engine to the radiator where it will be cooled before returning to the engine through pipe 7 and coupling 8. A part of this water may be bypassed to heater` 16,and a part to radiator 6 but when the temperature of the` water is too high for efficient operation of the engine the flow to the heater is entirely cut oli' and radiator 6 functions to lower the temperature until a part or all of the circulating water is again passed through the heater. A slotted connection 29 may be adjustably connected to rod 22 and bell crank 21 to permit automatic movements of the parts without causing locking engagement of -catch 23 with board 24. A water overflow pipe 30 may also be connected to pipe18 or some other part of heater 16, and the top of this overflow pipe may have an air opening or vent 31 to prevent siphoning of the contents of the system.

In Fig. 4 I show a water cooling and heating system in connection with an engine 32 having a water-circulating pump P, the return pipes 33 and 34 from radiator 35 and heater 36 being connected to the intake side of the pump, and the discharge side of the `pump beingconnected by a pipe 37 with coupling member 38. All the other parts correspond to the parts in the structure previously `described and are designated by the same numerals and characters. In Fig. l the heater is shown in front of the drivers seat. Obviously the heater may be located wherever most convenient and desirable. Also, two or more heaters may be used with this system, and the water may be'heated to a high temperature for a plurality of heaters before causing the thermostatic device to by-pass the water through the cooling radiator.
